Mechanistic features of reduction of copper chromite and state of absorbed hydrogen in the structure of reduced copper chromite

Russian Journal of General Chemistry, 2008
The review discusses the experimental data on the unusual mechanism of the reduction of copper cations from the copper chromite, CuCr2O4, structure. Treatment of copper chromite in hydrogen at 180–370°C is not accompanied by water formation but leads to absorption of hydrogen by the oxide structure with simultaneous formation of metallic copper as ...
